The Diaguita´s teritory, mainly the valleys, was divided into two. The upper and middle part, and the lower part.
Each half recognized a chief or cacique who ruled over minor chiefs.
Gerónimo de Vivar, while refering to the Aconcagua valley, says:
«The Lords of this valley are two; one is Tanjalombo, who overlooks half of the valley down to the sea; and the other Cacique is Michimalongo, whose domain and rule covers the other half of the valley up to the mountains, overlooks and dominates half of the valley and reaches the mountains.»
Toward the XVIIIth century, the Diaguitas had been assimilated by the Hispanic Creole society. Nowadays, almost nothing remains of their beliefs, traditions or cultural values.
